GENERAL DESCRIPTION
The TDA1552Q is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package.
The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration. The device is primarily developed for
car radio applications.
Features
• Requires very few external components
• High output power
• Low offset voltage at outputs
• Fixed gain
• Good ripple rejection
• Mute/stand-by switch
• Load dump protection
• AC and DC short-circuit-safe to ground and V
